从 JTextPane 中的任何偏移量获取样式
有没有办法获取 Style、样式名称，或者甚至将 JTextPane 某个位置的 Style 与我给出的样式进行比较插入时的文字？因为出于我的目的，我创建了自定义 JTextPane、StyledDocument 和 DocumentFilter。因此，我可以选择 Style 用于常规字母，而另一种样式用于数字。我还设置了切换按钮，切换时将 DocumentFilter 设置为不同的数字格式，而未定期切换数字格式，因此最后您无法仅根据 JTextPane 的 getText 来区分哪些数字受到影响() 方法。因此，唯一的方法是比较我将常规数字样式和特殊数字样式作为常量的样式。我唯一需要想到的是如何为每个角色获取风格。
我知道有 JTextPane's 方法可以从插入符的位置获取 AttributeSet，称为 getCharacterAttributes() 但我认为这对我的问题没有用。
是否需要包含代码示例？我觉得不难想象。如果你想要我，我会把它包括在内。
任何意见将不胜感激。谢谢！
Is there a way to get Style, a style name or just even compare whether Style at a certain position of JTextPane with the style I gave the text when inserting? Because for my purpose I created custom JTextPane, StyledDocument and DocumentFilter. So I could choose Style to be used for say regular letters and another Style for numbers. I have also toggle button which while toggled sets DocumentFilter to format numbers differently and while not toggled numbers format regularly so at the end you can't distinguish which numbers have been affected just according to JTextPane's getText() method. Therefore the only way would be to compare styles which I have both regular and special number style as constants. Only thing I need to come up with is how to get Style for each character.
I know there is JTextPane's method to get AttributeSet from the caret's position called getCharacterAttributes() but I think it's no use for my issue.
Is it necessary to include code example? I don't think it's difficult to imagine. If you want me I will include it though.
Any input would be appreciated. Thanks!

尝试调用
StyledDocument.getCharacterElement(pos)获取该位置的字符元素，然后调用Element.getAttributes()获取其属性集。AttributeSet包含可以使用样式常量。Try calling
StyledDocument.getCharacterElement(pos)to get the character element at that position and then callElement.getAttributes()to get its attribute set.The
AttributeSetcontains styles which you can retrieve using methods provided byStyleConstants.
